History

Leopardstar announces at a Gathering that Hawkpaw and his sister, Mothpaw, have become warriors in RiverClan, with the names Hawkfrost and Mothwing. His former mentor was Leopardstar. When some warriors from RiverClan protest, Leopardstar tells the story of how the rogue, Sasha, stayed in RiverClan with her kits, Hawkpaw and Mothpaw. For a while Sasha thinks of joining the Clan, but later, she does not think the life of a Clan cat suits her, so she leaves, but her kits stay with RiverClan and receive their Clan names. Leopardstar says that they will not be disloyal just because they are former rogues, seeing as many of ShadowClan's warriors were once rogues, and pointing out that ThunderClan is now led by a former kittypet. After the Gathering, Firestar approaches Hawkfrost to tell him that the fuss about his heritage will be over soon, and Hawkfrost replies that he will work hard to defend his Clan.

Hawkfrost is seen on a patrol with Mistyfoot watching WindClan drink from the river, to make sure that they don't steal prey. Hawkfrost says something urgently to Mistyfoot, but she shakes her head to whatever it is. The RiverClan patrol greets a ThunderClan patrol consisting of Leafpaw and Sorreltail, and Hawkfrost greets them politely. Leafpaw thinks that Hawkfrost reminds her of someone else she knows, but can't think of who. Mistyfoot asks if they have seen any sign of Stormfur and Feathertail, who have gone missing, and she is shocked to learn that ThunderClan is missing cats too: Brambleclaw and Squirrelpaw. Hawkfrost suggests that they ask other Clans if they are missing cats as well. The subject soon turns to the fact that WindClan has continued drinking from the river even though the drought on their territory is over, and Hawkfrost ferociously says that they should be driven off, but Mistyfoot tells him that Leopardstar has forbidden hostile actions and she will keep her word even if Tallstar doesn't. Hawkfrost concedes to her logic, but still seems angry.

At a later Gathering, Hawkfrost asks Leopardstar if he may speak. He says that he saw WindClan warriors stealing fish from the river when they were only supposed to be taking water. He claims to be alone at the time, so no other warrior could verify his words. Tallstar is indignant that his Clan is accused of stealing, but Leopardstar grows angry when he accuses Hawkfrost of lying.

As clouds start to cover the moon, some warriors try to calm the commotion; Firestar asks Hawkfrost if he might have been mistaken and Hawkfrost admits that he could have been dazzled by the sunlight on the water, though he still thinks he saw what he saw.

Leafpaw sees Hawkfrost at the head of a RiverClan patrol after leaving RiverClan territory. He stops to talk with his sister, Mothwing, who is near the border, but never once glances towards the ThunderClan border. Leafpaw looks at his massive shoulders and strong muscles and is glad that he had not caught her trespassing. She thinks to herself that he keeps strictly to the warrior code, and is unlikely to listen to her explanation. She once again, feels as if he reminds her of some other cat, but is unable to think of whom it might be.

Later, when Mothwing lets Leafpaw eat a RiverClan fish, they both scent Hawkfrost at the same moment. Mothwing immediately pushes the ThunderClan apprentice into a hiding spot, and confronts her brother. Hawkfrost stops to talk with Mothwing, and Leafpaw hears him talk about keeping an eye on WindClan. He claims that he knows they are stealing fish, and one day he would catch them in the act. Mothwing points out that WindClan would be more likely to fish near Fourtrees, if they were fishing at all, but Hawkfrost insists that they're guilty. He then comments that he can smell fresh ThunderClan scent, causing Leafpaw to shiver. Mothwing points out that it would be odd if he didn't scent ThunderClan, since the border was so close by. Hawkfrost grunts, and then says that something wasn't right in the forest. He says cats have gone missing from the Clans, besides Stormfur and Feathertail. He has no idea what was going on, but plans to find out. Mothwing reminds him that nothing was wrong in RiverClan, so he shouldn't care. But he tells her to not be so mouse-brained and reminds her that this was a chance to make RiverClan great. If the other Clans are weak, they could take over the whole forest. Mothwing is disgusted, and asks him who he thinks he is and compared him to Tigerstar. Hawkfrost then responds by saying that there are worse cats to imitate. Mothwing reminds Hawkfrost of Tigerstar's fate, but Hawkfrost insists that he has learned from his father's mistakes. Sasha had told them enough about Tigerstar; he broke the warrior code, and he deserved to fail. Hawkfrost then insists that he can smell fresh ThunderClan scent. He mutters to himself that he would claw up any warrior that dared stray across the border. Mothwing, in order to save Leafpaw, insists that he's right, and leads him away from her friend's hiding place. Leafpaw acts upon the opportunity and races towards the border.

As she turns back, she sees Hawkfrost investigating her hiding place, growling. Once again, she feels as if he reminds her of some other cat, but can't figure out whom.

When Leafpaw and Sasha are trapped in Twoleg cages, Leafpaw tells her that she knew Mothwing. Sasha asks if she knew Hawkfrost as well, sounding as worried as a Clan queen would be about her own kits. Leafpaw, who is uneasy speaking about the tabby warrior, tells Sasha that he had been fine the last time she had seen him, and Sasha lets out a sigh of relief.

Hawkfrost is seen when the Clan leaders and warriors gather at Fourtrees to witness its destruction and wait for the dying warrior sign from StarClan. It is revealed that Hawkfrost is RiverClan's deputy now, as Mistyfoot was captured by the Twolegs. He says that the other Clans should leave the forest to avoid starvation, but RiverClan will stay as they are safe from Twolegs and have enough food. Brambleclaw suspects him of wanting to take over the territory of other Clans. When Mistyfoot is freed and returns to the Clan, Hawkfrost loses his position as a deputy.

When Firestar's patrol finds Sasha on ThunderClan territory and chases her out, they are confronted by Hawkfrost. Sasha reveals that Tigerstar is the father of Hawkfrost and Mothwing. Firestar, Brambleclaw and Squirrelpaw are shocked on hearing this. They later discuss about him and some cats fear that Hawkfrost will share his father's ambitions of taking over the forest, but Firestar says he is no threat to them. However, Squirrelpaw is still suspicious of the RiverClan cat.

When Leafpaw visits the RiverClan camp, Hawkfrost appears and says that Tigerstar's fault was being loyal only to himself, while he is loyal to the Clan and lives by the warrior code. He says that he will be the most powerful cat in RiverClan, and all cats will respect him. Leafpaw is taken aback by his arrogance and ambition, and decides that he cannot be trusted.

As all four Clans finally prepare to leave the forest, Sasha asks Hawkfrost and Mothwing to stay in the forest with her. Hawkfrost declines, most likely because he plans to become leader of his Clan later, but he doesn't exactly make that clear. The two siblings say goodbye to their mother for the last time, and it is revealed to all cats that Tigerstar is their father. Some cats are frightened, but Leopardstar says they are loyal warriors, and Hawkfrost states he would never desert his Clan.

During the journey, Brambleclaw, Squirrelpaw and Leafpaw hunt in the moorland and Hawkfrost comments on their poor hunting skills. They are suddenly attacked by dogs, and Hawkfrost helps Brambleclaw drive the creatures away.

Hawkfrost is seen in the Tribe of Rushing Water's camp, looking relaxed as he watches Mothwing check Morningflower's pelt for fleas.

Hawkfrost's ambitions continue to grow. He argues several times with Mistyfoot due to being envious of her rank in the Clan. Even so, the other RiverClan warriors trust and respect him, and he continues to have several supporters who still believe he should have stayed deputy when Mistyfoot returned.

When Brambleclaw, Squirrelflight and the others return to the temporary camp after their mission to discover the lake, he is friendly toward Brambleclaw, and thanks him for going with the patrol. Squirrelflight, however, is still suspicious of him because she knew Leafpaw didn't trust him, and has an argument with Brambleclaw over him. This later leads to the end of their relationship.

Hawkfrost takes a patrol to explore the island in the lake, and suggests that RiverClan should use it as a camp, as it can be defended easily. Mistyfoot disagrees because she had found a good camp for them already. Hawkfrost argues with her and openly challenges her authority. Leafpaw thinks that Hawkfrost must feel very confident of his place in the Clan. In the end, Leopardstar decides that they won't set up their camp on the island and they would live in the territory Mistyfoot found.

It is later mentioned, after the Clans have settled into their new territory, that Hawkfrost and Blackclaw drove a badger from their territory.

Soon after, Tigerstar begins to visit Hawkfrost and Brambleclaw in their dreams. The two brothers start to meet in the waking world as well, and they develop a close friendship. As Firestar is still refusing to appoint a new deputy in the hope that Graystripe would return, Hawkfrost suggests Brambleclaw try to impress Firestar and show him that he should be deputy. He also urges his brother to convince Firestar Graystripe was not returning, so he would have to name a new deputy.

When there is a dispute about who should be next WindClan leader after the death of Tallstar, Hawkfrost sides with Mudclaw, and helps him lead a revolt against Onewhisker by leading some RiverClan and ShadowClan cats to help him in battle. During the fight, ThunderClan gets involved; on the shore across from the island, Mudclaw attempts to kill Brambleclaw, but Hawkfrost saves him. Mudclaw continues to tell Brambleclaw that Hawkfrost had promised to help him fight against Onewhisker if, once Mudclaw was leader, he made Hawkfrost deputy of WindClan. Later, they planned to take over RiverClan. Hawkfrost denies this, and Brambleclaw believes him. Lightning strikes a tree and it falls on Mudclaw, killing him instantly, and creates a bridge to the island. Hawkfrost accepts this as a sign from StarClan, and formally apologizes to Onewhisker.

Hawkfrost chases away a badger from the RiverClan territory, and when the RiverClan kits stumble upon the toxic Twoleg waste, Hawkfrost helps Blackclaw to build a thorn barrier around it. He thanks Leafpool when she reminds him to wash his paws in a stream. He also notes that the incident with the toxic waste happened because the patrols were not organized properly. Thus, he criticizes Mistyfoot's job as deputy practically to her face, trying to undermine her authority.

Hawkfrost's friendship with his brother Brambleclaw grows, and they meet both in the waking world at Gatherings and in the dreams of the Dark Forest. He promises to follow in his father's pawsteps, and that he will do anything Tigerstar asks to become leader. Squirrelflight and Leafpool still believe that he is untrustworthy, but the other cats do not have any problem with him, and he is seen as an excellent warrior.

Hawkfrost learns about the badger attack on ThunderClan when he meets Brambleclaw in the Dark Forest, and he is concerned about his brother. He and Tigerstar offer Brambleclaw advice on becoming deputy, suggesting that he should manipulate Firestar, make a good impression on him, and make friends with Daisy's kits so he can have an apprentice. The three cats practice battle training in the Dark Forest.

Trying to weaken ThunderClan so that his brother could become deputy, Hawkfrost tells ShadowClan about the badger attack, and ShadowClan attacks ThunderClan; however, they are defeated when Birchpaw carries a message to the camp for backup patrols.

Hawkfrost is not pleased when Stormfur returns to RiverClan, as he believes that he has much better chances of becoming a deputy than him. He pressures Mothwing into telling about a fake sign about a stream blocked by two pebbles, interpreting it openly to mean that Stormfur and Brook should be exiled from RiverClan for the good of all. He argues with his sister and it is revealed that it was him placing the moth's wing sign on the night when Mudfur asked for StarClan's guidance in the selection of his future apprentice, and he uses this secret to control his sister. Later, he provokes Stormfur into a fight, thus making Leopardstar exile the other warrior from RiverClan. Brambleclaw sees this as a tactical plan to become the next deputy.

Hawkfrost shows hostility towards Brook when she chases a squirrel over the RiverClan border into ShadowClan territory and reports her to Leopardstar. He explains in full detail Brook's deed, and how she almost got hit by a monster on the Thunderpath, maliciously adding a comment about how he wished it hadn't missed her, and reminding the Clan of Mothwing's false sign. Most of the cats seem to agree with Hawkfrost, and Leopardstar is finally convinced to send the Tribe cats on their way, after Hawkfrost provokes Stormfur and he lashes out at him. Hawkfrost believes that he will become deputy then with no competition if Stormfur is exiled. The former Tribe cats have not gone far when they are taken to the ThunderClan camp by Brambleclaw.

When Brambleclaw is finally made deputy, Tigerstar tells his sons that they are destined to rule the forest. He says that Hawkfrost should take over RiverClan and ShadowClan, while his brother will control the other two Clans, and they start making plans about how to do it. Hawkfrost suggests that once they are in charge, they should kill the other two leaders at a Gathering when they are all trapped on the island, and take over their Clans. He also suggests that they should continue the discussion when they are awake, and Brambleclaw agrees to meet him in two days, at sunrise, near the ShadowClan border.

Before they meet, Hawkfrost lures Firestar into a fox trap, so that Brambleclaw can finish him off easily and become leader in his place. However, Brambleclaw chooses to save his leader instead, because of his loyalties to Firestar, and gets him out of the trap. He tells Hawkfrost to go back to RiverClan, saying that he does not want to hurt his brother. Hawkfrost attacks him, but he is killed in the fight, his neck pierced by the stick of the fox trap. Thus, Leafpool's prophecy of "blood will spill blood" is fulfilled because they are half-brothers. The other part of the prophecy, "the lake will run red", is when Hawkfrost's blood spills out into the lake, turning the water red. Before he dies, Hawkfrost promises revenge, and reveals that there is a traitor in ThunderClan who helped him trap Firestar. He then staggers and collapses beside the lake and dies. It is revealed that Hawkfrost's spirit whispered in Brambleclaw's ear, saying how this was not over and they would meet again.

It is revealed that most Clan cats do not know how Hawkfrost died; they were only told that he was found dead on ThunderClan territory by a patrol, and his body was taken to RiverClan where his Clanmates mourned him.

Hollypaw mentions him when trying to convince Ashfur and Lionpaw that Firestar should make Graystripe deputy again, saying that he was only deputy until Mistyfoot returned.

Hawkfrost appears with Tigerstar when they try to convince Jaypaw to train with them, but Spottedleaf appears and takes him away from them.

Hawkfrost and Tigerstar are seen to be watching Lionpaw with interest.

He is furious with Lionpaw when he teaches Heatherpaw, the pretty WindClanapprentice he had been meeting with secretly in the tunnels underneath their territories one of the battle moves Tigerstar had taught him, saying that he had just taught an enemy a battle move. When Lionpaw protests that Heatherpaw is not an enemy, he hisses and asks him what he will do if she uses the moves against him one day. Lionpaw says that Heatherpaw will never do that, and says that he thinks Tigerstar and Hawkfrost didn't care about his meetings with Heatherpaw. Hawkfrost growls that they had admired his independence, and had only thought it was a harmless kit-friendship. Hawkfrost tells Lionpaw to take advantage of the tunnels and use it for an attack on WindClan to get more territory. Lionpaw replies that they already had enough territory and prey. Hawkfrost states that WindClan changed since Onestar became leader, and that ThunderClan was terrified of them, since Firestar is too scared to ask them what happened to Hollypaw, making Lionpaw suspicious that Hawkfrost knows something about his sister's disappearance. Before Lionpaw can ask, Hawkfrost disappears.

He and Tigerstar later tell Lionpaw how proud they are for ending Lionpaw's friendship with Heatherpaw.

He and Tigerstar continue to train Lionpaw, but he is not seen, nor Tigerstar, in one of Lionpaw's dreams. When Stormfur says Tigerstar's name while talking to Lionpaw, he thinks Stormfur knows about his meetings with Tigerstar and Hawkfrost, but he doesn't. During the battle against the rogue invaders, Lionpaw glimpses Hawkfrost's eyes shining as he fights.

He and Tigerstar visit Lionpaw in a dream and Hawkfrost tells him that he needs all the training they can give him. This sparks Lionpaw's annoyance because he thinks he fought well for the Tribe. Lionpaw realizes Hawkfrost and Tigerstar didn't see him in the mountains. Tigerstar orders Lionpaw to attack Hawkfrost and he does so. When Lionpaw tells them about the prophecy, he sneers at him for believing in the prophecy and attacks him, leaving him bleeding when he wakes up. Tigerstar is angry at his sneering even though he does not believe in the prophecy either and refuses to take him to the next training session with Lionpaw. Tigerstar is furious when he finds out that Hawkfrost was right and Lionpaw still believes he has the power of the stars in his paws.

Although not formally appearing, he is mentioned by Ashfur, when the tom reveals to Squirrelflight, Jayfeather, Hollyleaf, and Lionblaze that he was the one who had helped Hawkfrost from within ThunderClan to lure Firestar into the foxtrap, saying that he wanted for Squirrelflight's father to die so she would feel the same pain he felt when she chose Brambleclaw over him.

Hawkfrost, Tigerstar, and Brokenstar are seen looming over Poppyfrost's newborn kits, Cherrykit and Molekit. After this, Jayfeather and Lionblaze suspect that there will be a war between StarClan and the Dark Forest.

In the prologue, Hawkfrost is seen battle training with Breezepelt in the Dark Forest. As the two warriors battle, Hawkfrost manages to pin Breezepelt down with his claws. His opponent's eyes flash with panic as Hawkfrost begins to close his jaws around his throat; he is stopped by Tigerstar, who praises him on his good moves. Darkstripe arrives, remarking that Hawkfrost could match any warrior, and there weren't many cats with such strength and skill. Tigerstar silences him, hissing that Hawkfrost knows his own strengths. Brokenstar comments that while Breezepelt is quick, Hawkfrost is strong, and if their strengths are put together, they will be nearly unbeatable. Hawkfrost greets Brokenstar, baring his teeth, asking if he should take advice from him for not silencing Jayfeather. When Brokenstar responds that he didn't expect StarClan to fight so hard to save him, Hawkfrost says that he should never underestimate his enemy. As he says this, he stretches his forepaw forward, wincing.

When Hawkfrost suggests more training, Tigerstar shakes his head, telling Hawkfrost that he had another task for him. Narrowing his eyes, Hawkfrost asks what it was, and Tigerstar replies that he wanted him to recruit a certain apprentice. Menace edges Hawkfrost's mew as he asks if Tigerstar wanted him to visit her. As Hawkfrost turns away, Tigerstar calls out to him that he should have no trouble as she is ready.

One night, Hawkfrost walks in Ivypaw's dreams, appearing to her in a sunny meadow. She asks him if it is his field, but he says no, and casually offers to show her better hunting techniques. She accepts, and he shows her a few methods. He also asks about her sister, to which Ivypaw replies that Dovepaw is clever and funny. Before Ivypaw leaves, Hawkfrost tells her his name. She tells him hers, shortly before she departs.

When Ivypaw is assigned to help Blossompaw with her assessment and Blossompaw complains that Ivypaw is not a good hunter, Ivypaw hears Hawkfrost whisper in her ear that she is just as good a hunter as Dovepaw. She also feels him guiding her in the hunting move he showed her.

He continues to meet with Ivypaw in her dreams, showing her more battle and hunting moves. Ivypaw believes him to be a StarClan cat, and almost tells Dovepaw about his teachings, but she is too busy to listen, so she decides to keep it a secret so she can become as good a hunter as Dovepaw. Hawkfrost assures Ivypaw that she is not merely an echo of her sister, and can surpass Dovepaw if she works hard.

Eventually, Hawkfrost takes Ivypaw to the Dark Forest itself, and introduces her to Tigerstar. She is uneasy at first, but they convince her that they are trustworthy, and she continues her dream training there.

During the battle with ShadowClan, Ivypaw can feel his presence, even though she can't see him.

When Ivypaw returns to the Dark Forest after the battle with ShadowClan, Hawkfrost tells her that she fought well, but she got the move wrong on Scorchfur, and comments that she should never turn on two legs when she can manage on one. When Mapleshade attacks Ivypaw, Hawkfrost tells Mapleshade to let her go, and Ivypaw informs him that her sister, Dovepaw, knew that she was training in the Dark Forest. After Hawkfrost tells her that he would inform her if she was doing anything wrong, he introduces her to two Dark Forest Clanmates: Shredtail and Sparrowfeather. Afterwards, he supervises the training session with Thistleclaw.

The next time Ivypaw goes to the Dark Forest, she is attacked by Thistleclaw, but she fights him off so nicely that Hawkfrost praised her, and it is mentioned that praise from him is rare. Hawkfrost supervises a water training session, and Darkstripe tells him that he can partner up with his apprentice, since he is supervising.

Ivypaw strays into the Dark Forest, calling for Hawkfrost, after finding out the truth about the Dark Forest: that they aren't trying to help Ivypaw be a better warrior, but wanting to get her support as they try to destroy the Clans. Mapleshade appears, telling Ivypaw that Hawkfrost is busy, and that he wanted Mapleshade to train Ivypaw for the day.

Hawkfrost is seen managing a Place of No Stars battle session. He instructs them to all attack him at once, to show what they should have done. Then Brokenstar introduces Blossomfall to the other Dark Forest trainees, interrupting the session. Later he introduces Hollowpaw to Ivypool and tells her to teach the new apprentice a move or two before stalking off.

After Ivypool spies on Tigerheart, Hawkfrost finds her and shoos her away for training with the other apprentices.

When Ivypool requests to become a warrior for the Dark Forest, Hawkfrost is impressed with her bold request and replies that he knew she was special.

After Ivypool killed Antpelt's spirit to become a Dark Forest warrior, Hawkfrost tells her that he is glad that she became his apprentice, and that he is proud of her. Ivypool also notes that she sees a glint of fear in his eyes as they walk away. He also reminds her to train the apprentices before he leaves her.

This section needs expansion. You can help the Warriors Wiki by adding more info.

He is seen training the apprentices at the beginning of the book. Hawkfrost snarls at Ivypool when she cautions Birchfall and Redwillow to be careful while training. Curling his lip and staring at Ivypool, he says that there was a war coming and it wouldn't be won with sheathed claws. Hawkfrost tells Ivypool that he thought that she was training the Dark Forest apprentices to be real warriors, not soft Clan cats. Birchfall bristles and says that Clan cats weren't soft, causing Hawkfrost to challenge him, asking why he was in the Dark Forest. When Redwillow tells him that the Clans needed them to be the best warriors, Hawkfrost nods slowly and adds that he could learn the skills only at the Dark Forest.

Flicking his nose toward Birchfall, Hawkfrost instructs him to attack Redwillow once more and to not stop at the first scent of blood. While he says this, he narrows his eyes at Ivypool. After Ivypool attacks Redwillow, she glances at Hawkfrost, whose eyes were glittering with approval.

During a meeting in the Dark Forest, Brokenstar kills Beetlewhisker. Afterwards Ivypool watches Hawkfrost walk up to Beetlewhisker's body and kick it viciously, commenting that he never trusted him. In the battle between the Dark Forest and the Clans, Tigerheart whispers something to Hawkfrost. Then Thistleclaw tells Ivypool to meet Hawkfrost on the far side of WindClan's camp. When Ivypool admits that she fights for the Clans, Snowtuft, Hawkfrost, and Thistleclaw attack her and drive her into the Dark Forest. Hollyleaf joins the fight while Tigerheart helps Ivypool, only to die of the wounds Hawkfrost gave her when she was brought back to ThunderClan camp.

After the final battle at ThunderClan's camp winds down, Hawkfrost tries to escape with his Dark Forest Clanmates, but Brambleclaw stops him. Ivypool attacks him furiously, aiming to avenge Hollyleaf's death, but Hawkfrost fights back fiercely and almost kills Ivypool. Brambleclaw kills Hawkfrost before he can do so, though, and his spirit fades permanently.

In this guide, Rock says that even before he knew who his father was, Hawkfrost wanted to take Leopardstar's place. It is said that Hawkfrost is clever enough to know that even though he is Leopardstar's favorite, it did not make him respected by his Clanmates.

Hawkfrost even tore off a moth's wing to convince Mudfur to take his sister, Mothwing as his medicine cat apprentice.

Hawkfrost does not appear in the book, but Tawnypelt mentions him when she is giving the reader a tour around the lake territories. She tells how he aided Mudclaw in his rebellion against Onewhisker when in WindClan territory. While crossing ThunderClan, she stops by the lake and tells how Hawkfrost died at the paws of Brambleclaw when he had tried to kill Firestar. She also states that so much blood flowed from Hawkfrost, it turned the lake red. This is a mistake, only Brambleclaw, Firestar, and Leafpool know what happened.

It is mentioned on Leafpool’s page that she witnessed Brambleclaw killing his half-brother, Hawkfrost, fulfilling the prophecy that blood will spill blood before the Clans were truly settled around the lake. He appears on Brambleclaw’s page. Tigerstar was scheming with Brambleclaw and Hawkfrost to destroy the weaker clans. At the last moment with the possibility of Firestar losing all his lives to Hawkfrost’s trap, Brambleclaw realized where his loyalties lay and killed Hawkfrost, fulfilling the prophecy.

He appears on Ivypool’s page. When Hawkfrost visited Ivypaw in a dream, offering to be a better warrior, Ivypaw said yes and Hawkfrost led her on nightly training sessions in the Dark Forest. Ivypaw shone and began training apprentices and was sought out for praise by Hawkfrost time after time. During the Great Battle, Hawkfrost cornered Ivypool, hissing vengeance for her betrayal of the Dark Forest. Hollyleaf leapt forward just as Hawkfrost gave the death blow and died saving Ivypool’s life.

He appears on Tigerstar’s page. In pursuit for revenge, Tigerstar walked in the dreams of Brambleclaw and Hawkfrost, training them and urging them to kill Firestar. Hawkfrost was eager to do whatever to please Tigerstar but Brambleclaw realized his loyalties lay with Firestar and he killed Hawkfrost. It is mentioned on Mudclaw's page that Mudclaw's most determined supporter was Hawkfrost, ever keen to stir up trouble. Hawkfrost warned Mudclaw that Onestar's reluctance to seize more territory beside the lake would leave WindClan hungry come leaf-bare.

Hawkfrost has his own page. He was Tigerstar’s other son and was born to a loner named Sasha. Sasha gave birth to her kits and tried to raise them alone away from the clans but after nearly losing the whole litter, Sasha brought her kits to RiverClan, and left them to survive as Clan cats. Before he even met Tigerstar, Hawkfrost wanted Leopardstar’s place. He trained harder and was rewarded by temporarily being named deputy. He was clever enough to know that being Leopardstar’s favourite did not mean full respect so he plotted to make Mothwing medicine cat. Tigerstar saw the potential and started training him in his dreams, encouraging to uprise against Onestar and lying about ever being a part of it. Tigerstar encouraged Hawkfrost to plot to kill Firestar but instead, Hawkfrost was killed instead. Hawkfrost walked in the Dark Forest, walking in cats’ dreams and encouraging them to rise above the code. He sought out Ivypaw and watched with pride as she rose high. When he realized she was with the Clans, he tried giving the striking blow but Hollyleaf endured it, killing her instead. He was pursued back to the Dark Forest by a fearsome patrol of warriors.

He appears on Mothwing’s and Willowshine’s page. Mothwing objected to Hawkfrost’s method of convincing Mudfur to mentor her as a medicine cat. Hawkfrost’s threat to reveal her terrible secret forced Mothwing to make false prophecies for her. It is mentioned on Stormfur's and Brook's page that Hawkfrost, afraid that Stormfur would be chosen as deputy over him, cast doubts over his loyalty and had him driven out. He is lastly mentioned on Fallen Leaves' page. Fallen Leaves was there when Hollyleaf died, struck down by Hawkfrost.

Hawk is seen on the front cover playing with his siblings Moth and Tadpole. The three kits go off to find Ken while their mother, Sasha, is off to hunt. They climb into a abandoned Twoleg Nest. It starts filling up with water and Tadpole is able to open a window, but slips and drowns in the flood. Hawk then keeps yelling for his dead brother, and when he finds out Tadpole had died in the flood he lets out a yowl of grief.

Moth, Hawk and Sasha go to a barn which Pine suggests, but they are attacked by the cats living there, Hawk's ear getting cut in the process. Quickly, they leave for RiverClan, and Sasha leaves her kits there, but decides Clan life isn't for her.

Hawkfrost doesn't personally appear, he is mentioned often. Leafpool remembers the prophecy she was given when the Clans arrived at the lake, and how it was fulfilled when Brambleclaw killed Hawkfrost, making the lake run red with his blood, while defending Firestar.

She finds Brambleclaw sitting on the shore, staring out at the lake. Leafpool asks him if he was thinking about Hawkfrost, to which he replies that he was.

Hawkfrost is only briefly mentioned by Tornear, Brambleclaw, and Cloudtail. When the WindClan warrior, Tornear, mentions that Hawkfrost was not as welcoming to kittypets like ThunderClan was, Cloudtail becomes furious, and growls that Hawkfrost had plotted to murder Firestar. He also says that they wouldn't invite a murderer into camp, and let him have first pick of the fresh-kill pile.

Tornear responds that ThunderClan hadn't a chance to do that, as Hawkfrost stabbed himself with a piece of wood, and ended up rolling into the lake, dying in the process. Brambleclaw, upon hearing this, retorts that Hawkfrost's death was none of Tornear's concern, and that RiverClan was well rid of him, also calling him a traitor to the warrior code.

Leafpool remembers seeing Brambleclaw standing over Hawkfrost's body after he tried to kill Firestar by luring him to a fox trap. Brambleclaw saved his leader by fighting his half-brother to the death. Brambleclaw is still recovering from that day, covered in many scratches Hawkfrost gave to him. Leafpool thinks it's Brambleclaw's fault as he was in the Dark Forest with Hawkfrost and Tigerstar. She still cannot figure out why he freed Firestar and killed Hawkfrost. Brambleclaw explains to Leafpool he knows she saw him in the Dark Forest with Tigerstar and Hawkfrost, and promises it won’t happen again. Brambleclaw says Hawkfrost is dead because of him.

Ivypool mentions that Hollyleaf saved her from Hawkfrost, who was trying to kill Ivypool. She mentions this again later. It said that Ivypool is treated favorably by the cats that saw her attack Hawkfrost. During a meeting at an island, Dovewing tells Ivypool to tell about how Hawkfrost recruited her. Ivypool does, telling the leaders Hawkfrost went to her and made her believe that the best thing for her Clan is to train in the Dark Forest. He made Ivypool feel important. She then overheard him and Tigerstar making plans to attack, so became a spy.

Trivia

He has been mentioned with both amber eyes[28] and dark blue eyes.[29]

He has SkyClan blood, because his great aunt, Spottedleaf, is descended from Spottedpelt and because his father, Tigerstar, is descended from Gorseclaw.[30]

He has ThunderClan blood, because his father, Tigerstar, was born in ThunderClan.[31]

He has kittypet blood, because his mother, Sasha, was formerly a kittypet.[32]

In The Sight, he is mistakenly referred to as being RiverClan deputy when he died, even though Mistyfoot had taken back her position long before that.[33]

In Cats of the Clans and The Ultimate Guide, it is mentioned Hawkfrost wanted to take over the Clans even before he knew who his father was. This is false, as in Return to the Clans, Sasha told Hawkfrost and Mothwing who their father was before they joined RiverClan.[34][35]

A continuity error is in After Sunset: We Need to Talk. In the play, it is apparent that all cats seem to know that Hawkfrost attempted to kill Firestar,[36] while in The Sight, this fact is unknown.[33]

Vicky has said that Hawkfrost and Ivypool did not ever love each other.[37]

"Don't worry; I'm not one of the cats who thinks cats from different Clans shouldn't have anything to do with one another. I saw what happened with Tawnypelt. It's tough to have loyalties divided. We all have friends in other Clans now, and yet we have to act as if being rivals is the only thing that matters."

"Hawkfrost is fearless. He proved that when he drove a badger out of RiverClan territory. And he showed great wisdom when he helped his sister become a medicine cat. Her support will smooth his path to leadership. He knows that power comes only to those who want it most."
